Zinc oil additives

The whole reason detergents were added, IMO was because people either would not change their oil, ir did it way less frequently than they should. I think you could run the old single weight non detergent oil as long as there was sufficient ZDDP for the type of lifter you run. That's my opinion and I'm stickin to it.

Yep.
What does detergent in motor oil do?

Detergent oils have enhanced additive packages blending in them to prevent rust, break down engine sludge and stabilize acids to prolong oil life. With a newer engine or an engine that has been running on a detergent oil for years this is the right choice, it keeps your engine cleaner and running smoothly.Jan 20, 2020
